76095: kv: don't pass clock information through Raft log r=nvanbenschoten a=nvanbenschoten

This commit eliminates the primary mechanism that we use to pass clock information from a leaseholder, through Raft log entries, to a Range's followers. As we found in #72278, this was only needed for correctness in a few specific cases — namely lease transfers and range merges. These two operations continue to pass clock signals through more explicit channels, but we remove the unnecessary general case.

The allows us to remote one of the two remaining places where we convert a `Timestamp` to a `ClockTimestamp` through the `TryToClockTimestamp` method. As outlined in #72121 (comment), I would like to remove ability to downcast a "data-plane" `Timestamp` to a "control-plane" `CloudTimestamp` entirely. This will clarify the role of `ClockTimestamps` in the system and clean up the channels through which clock information is passed between nodes.

The other place where we cast from `Timestamp` to `ClockTimesatmp` is in `Store.Send`, at the boundary of KV RPCs. I would also like to get rid of this, but doing so needs to wait on #73732.

76163: bazel: remove old protos when generating new ones r=ajwerner a=ajwerner

This is what the Makefile did. It was painful to have the old onces because
they'd lead to spurious diffs.

76166: sql: support version numbers on descriptor validation r=fqazi a=fqazi

Previously, the descriptor validation code did not
take a version number, so it was not possible to version
gate new validation logic. This was inadequate  because
when new fields are introduced we don't want their validation
to kick in for certain cases like the debug doctor, such as any
new fields with non-zero defaults. To address this, this patch add supports
for version numbers inside the validation, and updates unit tests
to pass this in as well. It also adds a new option on debug doctor
to run a version of validation.

Release note (cli change): Add new optional version argument
to the doctor examine command. This can be used to enable /
disable validation when examining older zip directories.

76191: gazelle: exclude `.pb.go` files r=dt a=rickystewart

Should prevent Gazelle from getting confused and adding these to `srcs`.

76192: ci: make sure extra env vars are set for `roachtest` jobs r=rail a=rickystewart

We [need these](https://github.com/cockroachdb/cockroach/blob/5e7690d6da09821ff431ef32fe8d1430d05aed9f/pkg/cmd/internal/issues/issues.go#L159-L171).

76194: tree: remove TODOs about bytea/float cast volatility r=mgartner a=rafiss

These comments aren't needed, since the current cast volatility is
correct, as far as I can tell.

We might want to report this as a bug in Postgres if it describes these
casts as immutable incorrectly.
